In genetics, a selective sweep is the process through which a new beneficial mutation that increases its frequency and becomes fixed (i.e., reaches a...

Additionally, the effects of density-dependent processes, epistasis, and soft selective sweeps on the maximum rate of substitution have been examined. By looking...

genetic variation, a "soft sweep", the rationale does not apply, because the allele is no longer rare in the beginning of the sweep. In fact, recessive...
